ration outlined on the shade, the outline design being the decoration ofthe shade when the back side thereof is not illuminated, but when lightshines on the back side of the shade the decoration is formed by linesof light rays passed therethrough.

Particularly it is an object of this invention to provide a shade formedof an opaque stencil, the slots ofwhich represent a detail line designof a decoration, and a transparent covering on one face of the stencilhaving a large outline design thereon corresponding substantially to theboundaries of .the design of the stencil for decorating the shade whenthere is no light shinning thru the stencil,

other times the light rays passing through T the slots and openings ofthe stencil forming the detail line design within the said boundaries;the said shadebeing' adapted to be bent and arranged in a desired formsuch as a lamp shade, to form a different decoration on the lamp atdaylight than the design and decoration appearing thereon at artificiallight within the lamp.

In this speclficatlon and the annexed drawing, the invention 15illustrated in the form considered to be the best, but it is to beunder-:5

stood that the invention is not limited to such form, because it may beembodied in other forms; and it is also to be understood that in and bythe claims following the description, -15 it is desired to cover theinvention in what-- soever form it may be embodied.

The invention is clearly illustrated in the accompanying drawing whereinFig. 1 is a face view of aflat shade con-.1 0 structed in accordancewith my invention.

In its general 'organiz ation the invention includes an opaque stencil6, having a design partly cut out therefrom and bent away-from the planeof the stencil so as to leave a clearance 7 adjacent the edges of thecut out design, toallow light rays to shine therethru. V

The bent away flaps 8 are formed to repre=- sent parts of the detaildecoration desired, such as the petals like. 7

or leavesof flowers, or the On the smooth'side of the stencil 6- andover the'cut out design,is suitably secured a transparent layer sheet 9,on which the said light rays reflect the lines of the design as cut outfrom the stencil 6. The' transparent layer 9 may cover the entire outersurface of thestencil, or 'it'may' be'rarranged only op positetheportions of the stencilwhe re the designs are cut. I In bothinstances the transparent layer is sov arranged and colored-as tocorrespond to the-outer boundaries or contour of the particular groupdesigned onthe-sten cil.

illumination on the inside. face of the stencil 6. These areas outliningthe general design are surface shaded for color in the drawings toillustrate the attractive decoration that is obtained thereby. I

so i

form the illuminated decoration of the. shade. I

The shade A shown in Fig. 1 can be hung .in front of a window pane orthe like as a.

decorative picture or the like, and-present, a difierent design at ni htthan in day light -.when. the sun ishines through thejstencil 6;

The same efltect'canbe accomplishedby arti- In Fig. 3 the shade is bentinto a, frustoconical lamp shade B and the large area or boundary designis the day light decoration of the shade, while the stencil design 12reflects within the area 11 only when the electric light within theshade is illuminated.

The fine decoration reflected into the area 11 is also shaded by reasonof the partial reflection of light from the convex side of the flaps 8.Near the clearance 7 the light shines bright, while gradually shadedlight spots are reflected to appear adjacent each clearance 7, givingdepth to the design.

The section in Fig. 2 is taken on the stencil at a point where thedesign represents a pansy '14, the petals 16 of which are cut out ":Ofthe 'stencilat their outerperiphery and are bent away toward the back-ofthe stencil, 7

-all petals converging to the center of the pansy. Thus, when light isreflected on the stencil, finely shaded petals are reflected on thecolored area 14 to coact therewith in presenting an attractiveilluminated design.

"In some instances, if so desired, the inner surface of the stencil 6may be also covered by a transparent sheet of material. In allembodiments, the outer layer 9 presents a decorative design when nolight is shining on the back of the stencil, and when light is shiningon the stencil, the decoration changes, and a novel and differentilluminated decoration appears within the decorative areas of the outerlayer 9.

Having thus described this invention, what I claim and desire to secureby Letters ,Pat-

ent is:

A shade comprising an opaque stencil having a design cut thereon, theedgesof the design being bent away to the-back side of the stencil outof the plane of'the same to per- 1 'mit light rays from the rear of thestencil-to shine through, a transparent-cover on the other face of thestencilhaving a design thereon substantially corresponding to theboundaries of the group of stencil design to form a decoration of theshadeindependently -ofthe stencil cutsat one time," and coacting withthe stencil design reflected thereon through the cut edges of thestencil design from a source of light behind the'stencilto form adifferent and illuminated decoration.

2. A shadecomprisingan opaque stencil having a design cut thereon, theedges of the a design being bent away to the back side of the stencilout of the plane of the same to permit llght rays from the rear of thestencilto shine through, a transparent cover on the outer'face of thestencil having a design therer on substantially corresponding to theboundaries of the group of stencil design to form a r decoration of theshade independently of and different from the stencil cuts at one time,

and coacting with the stencil design reflected 5 thereon through the cutedges of the stencil design from a source of light behind thestenoil,the stencil design forming detail lines to complement and shadethe'outline and face of the decoration on the transparent cover.

3. In a lamp shade an opaque stencil bent and secured in the shape of alamp shade, and a transparent covering on the outside surface of thelamp shade, saidcovering having a decorative design thereon to becomplemented by the stencil design reflected onto the covering when alight inside of the shade is illu- -minated,-the' design-on the coveringbeing formed by a plurality of separate areas representing substantiallythe outlines of the group designs cut in the stencil, so that thestencil designs 'are"reflected into the correspondingareas on thecovering, the edges of the stencil design being bent out of the plane
